One type of insulating film Which is used between .the contacts 4 sand 5: is in the form of a` thin disk such .as indicated at 7 .and as Will be understood itis necessary to introduceisuch a Ndisk orflinsu-lating filmfbetiveen the contact blades 4L and y5 ybefore the socket receptacle 16' isf -inserted- -into the receptacle head.

lrflhe device vherein shotvnis designed to facilitate the insertion of these insulating llms into position between the endsV 6 of the Contact blades. Said device comprises a body member adapted tobe introduced into the space between the separated portions or the blades 4 and 5, which body member has a film-delivery'- Ypassage that terminates'zadf jacent theends Y6,fme'ans for eedingv'lilms# separately into said passage, and means-toeject theV lilin rfrom the passage and V-Ytorce'. it

In the use of these socket receptacles it is desirable that the contacting faces of the ends 6 of the contact blades should have good contact surfaces. Vhen the film is fused or burnt it sometimes happens that a deposit will be left between the contacting faces which it is desirable to remove or sometimes these faces become corroded slightly. In order to clean the faces and provide clean contacting surfaces the side faces of the extremity of the eXtension l1 may be roughened or constructed to have abrasive qualities as indicated at 36. .With this construction the cleaning of the contact surfaces of the ends 6 of the blades can be accomplished by passing the portion of the extension ll which has the abrasive surfaces between the contacts one or more times.

After these surfaces are properly cleaned then the device may be inserted in operative position between the blades 4l and 5 and manipulated to place the filler in position as above described.

I claim:

l. A device for inserting insulating films between the bayonet blades of a socket receptacle, said device having a body adapted to be placed between the separated portions of said blades and provided with a delivery passage having its discharge end adjacent the portions of the blades between which the film is to be inserted, means for supplying insulating films to said passage, and means to eject each film separately from the passage and introduce it between the blades.

E2. A device of the class described comprising a body member having an extension adapted to be inserted between the separated portions of bayonet blades, said body member aving a delivery passage with its discharge end at said extension, means for supplying insulating films individually to said passage, and means to eject each film from the passage and force it between the bayonet blades.

3. A device of the class described comprising a body member having an extension adapted to be inserted between the separated portions of bayonet blades and provided with an edge portion to rest against the socket receptacle, said body having a delivery passage, the ldischarg-e end of which is situated adjacent the portions of the blades between which a film is to be inserted when said body member isA resting against the socket receptacle, means to supply insulating films to said passage and an ejector for ejecting each lm from the passage and force it between the bayonet blades.

4. A device of the class described comprisare. supplied to said passage, and an ejector f operating between said plates to deliver each film from the passage and into position be-` tween the bayonet blades.

5. A device of the class described comprising a body memberhaving two side plates spaced from each other, an ejector member situated between said plates and mounted for rotative movement, said ejector member forming with the side plates a. delivery passage having a discharge opening which is'situated adjacent th-e portions of bayonet blades between which a film is to be inserted when the body member is in operative position with relation to said blades, means to supply films to said passage, and means for actuating the ejector to force insulating films from the passage into position between the blades.

6. A device of the class described comprising a body member having an extension adapted to be inserted between the separated portions of bayonet blades, said body member having a delivery passage with its discharge end at said extension, means for supplying insulating films individually to said passage, and means to eject each film from the passage and force it between the bayonet blades, the side faces of said extension having abrasive qualities, whereby the contacting faces of the bayonet blades may be cleaned by passing the extension between them.

In testimony whereof, I have signed my name to this specification. Y
